Finding number of Cores of The Processor

[Akash]

Hi,
I am using getProcessTimes API for calculating CPU Usage
On a Multi-Core processor i have observed that the %CPU Usage that is
multiple of the number of cores of the processor
Is there any API in VC to find the number of Cores of a processor?
(PS: Without using WMI ie)

Yes, there are some apis.
ask on win32 api newsgroup to get them :

Take a look at GetSystemInfo()

to see if it provides what you need.

The NUMBER_OF_PROCESSORS environment variable tells you how many total
processors your PC has (number of CPUs times number of cores per CPU times 2
if hyperthreading is enabled)
